From 53c5bd72bae089616a3ca626b8af240481d70e6f Mon Sep 17 00:00:00 2001

Subject: [PATCH] Remove ucontext_t/rt_sigframe from kernel-abi
These were added in 18bb097736a1b728f1e5bfec972ca10f6e763d82 to help us determine
the sigmask effect of rt_sigreturn syscalls, but they're no longer needed
because we query the new mask via /proc instead.
Resolves #2237
